The Waste Isolation Pilot Plant stores nuclear weapons waste deep in underground salt caverns. There was an underground fire in February, followed by a release of radioactivity that contaminated 22 workers and shuttered the facility.

Supporters of a plan to profit from nuclear waste storage in southern New Mexico said this week that they hope to start collecting spent fuel rods from nuclear power plants soon. However, a recent decision from the Nuclear Regulatory Commission doesn’t eliminate all of the hurdles that the group would have to clear before there’s a chance of that actually happening.
